| IsdnIfIndex |
| Unique index of an Interface. |
| Number |
| The channel number. 0 is D-channel, 1..2 are the B- channels of a BRI module, and 1..31 are the B-channels of a PRI module. |
| State |
| Status of the Channel controlled either by the call control protocol or the physical state of the interface. Enumerations: - not-connected (1)
- connected (2)
|
| Type |
| Type of Channel.Setting this object to one of the leased values creates a new entry in the ifTable. Enumerations: - dialup (1)
- leased-dte (2)
- leased-dce (3)
- loopback (6)
- not-available (7)
|
| Bundle |
| Index of the bundle to aggregate multiple Channels to one interface. Not valid in dialup mode. Range: 0 to 255 |
| Throughput |
| Throughput of the channel in bits/second (64000 for B-channels, 16000 for BRI D-Channels. |
| ReceivedPackets |
| Count of received valid HDLC Frames. |
| ReceivedOctets |
| Count of received valid HDLC bytes. |
| ReceivedErrors |
| Count of received valid errors (can be detected by HDLC-Checksum-Errors). |
| TransmitPackets |
| Count of received valid HDLC Frames. |
| TransmitOctets |
| Count of received valid HDLC Frames. |
| TransmitErrors |
| Count of transmitted valid HDLC errors. Can occur when the transmitter can not be reloaded fast enough when transmitting large packets. This should only happen when the system is over encumbered. |
| ReceiveDiscards |
| Count of discarded received data frames. Can occur when the machine can not process fast enough the received frames. This should only happen when the system is over encumbered. |
| PhysicalBundle |
| Index of the bundle to aggregate multiple timeslots to one hyperchannel. Not valid in dialup mode. Range: 0 to 255 |
